NCT00363727
This study evaluates how effective a new formulation of a marketed drug is in increasing the time to onset of dyskinesia (abnormal twisting, writhing movements) in patients with Parkinson's Disease who have been taking levodopa for less than 2 years.
NCT01280123
This is a multi-center, double-blind, placebo controlled clinical trial of two dosages of oral pioglitazone (15 milligram(mg) and 45 milligram (mg)) for safety, tolerability, and futility. Subjects who are on stable dose of rasagiline 1 mg/day or selegiline 10 mg/day for at least 8 weeks but no more than 8 months, will be randomized to one of two dosages of oral pioglitazone (15 mg and 45 mg) or matching placebo. The study will measure disease progression by the change in total Unified Parkinson's Disease Rating Scale (UPDRS) score between the baseline visit and 44 weeks.
NCT00449865
The purpose of this trial is to determine if the nutritional supplement creatine slows the progression of Parkinson's disease over time.
NCT00522379
The purpose of this study is to show Rotigotine dose response at four doses of Rotigotine used with L-dopa in treating advanced stage Parkinson's disease.
NCT00594165
The objective of this open-label extension is to assess the safety and tolerability of long-term treatment of the rotigotine patch in subjects with early-stage idiopathic Parkinson's disease.
NCT00601523
The general aim of this study is to obtain long-term safety and tolerability data on pramipexole ER, in daily doses from 0.375mg to 4.5mg once daily (q.d), in patients who have previously completed a pramipexole double-blind study in early PD (248.524(NCT00479401) or 248.636(NCT00558025) trial).
NCT00321854
This is a double blind, placebo-controlled clinical trial of 15 months duration designed to examine early Mirapex (pramipexole) treatment vs. delayed Mirapex (pramipexole) treatment in patients with new onset Parkinsons disease
NCT01744496
This trial is being conducted to compare the impact of Rotigotine and Placebo on Chronic Pain associated with Parkinson's Disease among patients with advanced stages of the disease.
NCT00936676
Eligible participants, who participated in the ADAGIO trial and who sign an approved informed consent form, will be enrolled into the study at their original study locations. participants who have stopped rasagiline therapy and in the opinion of the investigator will gain clinical benefit from restarting treatment can also be considered for enrollment in the Core follow-up study period. Use of any other anti-PD treatment is permitted as deemed necessary by the treating physician (according to the participants clinical status).
NCT00632736
To evaluate the safety profile of ropinirole XL during long-term treatment in subjects with early and advanced Parkinson's disease
NCT00144300
To determine if there is any difference in the presence of retinal deterioration in PD patients treated with pramipexole IR versus ropinirole as monitored by comprehensive ophthalmologic assessments from baseline to the end of study at two years.
NCT00357994
The primary objective of this study was to demonstrate the superiority of levodopa - carbidopa intestinal gel over treatment with optimized oral levodopa/carbidopa during 12 weeks.
NCT01076452
The goal of the second phase of the study is to determine if simultaneous bilateral subthalamic nucleus stimulation or simultaneous bilateral globus pallidus stimulation is more effective in reducing symptoms of Parkinson's Disease.
NCT00833690
The purpose of this study is to determine the safety and tolerability of inosine and its ability to raise urate levels in blood and cerebral spinal fluid in individuals with early Parkinson disease. This will determine whether it is appropriate to proceed with a larger study of inosine's ability to modify the rate of disability progression in PD.
NCT00056563
The goals of this study are to determine if simultaneous bilateral subthalamic nucleus stimulation or simultaneous bilateral globus pallidus stimulation is more effective in reducing symptoms of Parkinson's disease, and if deep brain stimulation or best medical therapy is more effective in improving Parkinson's disease symptoms
NCT02562768
This two-part study will evaluate how safe LY3154207 is and the effects it has on the body. Part A will include healthy participants. Each participant will receive daily doses of LY3154207 or placebo for 14 days. Part A will last approximately 4 weeks including a 17 day stay in the clinical research unit (CRU) and follow-up. Part B is contingent on the results of Part A. Part B will include participants with Parkinson's disease. Each participant will receive daily doses of LY3154207 or placebo for 14 days. Part B will last approximately 4 weeks including a 17 day stay in the CRU and follow-up. Both Part A and Part B will require screening within 30 days prior to the start of the study.
NCT01803945
This is a randomized, double-blind, placebo-controlled, multiple-ascending dose study of orally administered AVE8112 in patients with Parkinson's Disease (PD).
NCT02144220
The primary objective of this study is to evaluate the feasibility, efficacy and the value of providing care to individuals with Parkinson disease directly into their homes. The specific aims are: 1. To demonstrate the feasibility of conducting remote evaluations of patients with Parkinson disease nationally; 2. To measure the impact of remote care on each patient's ability to improve his or her quality of life (QoL) and better manage his or her Parkinson disease; and 3. To assess the long-term acceptability to patients in receiving ongoing care remotely via telemedicine.
NCT01738178
Parkinson's disease is a common neurodegenerative disorder in which patients experience progressive motor disability and many disabling non-motor symptoms. Recent studies have consistently found that people who do not use caffeine are at higher risk of developing Parkinson's disease. This suggests that caffeine may have potential as a treatment for PD. In a pilot study of caffeine for daytime sleepiness in PD, there was evident benefit on the motor manifestations of disease. There have been other lines of evidence that have suggested caffeine could be useful in PD. This study is to evaluate the efficacy of caffeine 200 mg BID vs matching placebo for motor and non-motor aspects of disease. This will be in three stages. In the first six-month stage, medications will be held constant, to see whether caffeine does have motor benefits. Then we will perform a four-year extension stage to define if the effects of caffeine persist (or even magnify), and to see if caffeine helps reduce dose of other PD meds and/or prevents their side effects. Finally, we will finish with a six-month stage in which we will place all patients on caffeine - this will allow us to assess caffeine's use in later disease, but more importantly, will assess whether early use of caffeine produces long term changes beyond its immediate effects.
NCT00986414
This phase IIb study is designed to determine the safe and efficacious dose or dose range of AFQ056 for the treatment of patients with moderate to severe Parkinson's disease with L-Dopa induced dyskinesias.
